Anatomical terms of neuroanatomy

The rostral interstitial nucleus of medial longitudinal fasciculus (riMLF) is a collection of neurons in the medial longitudinal fasciculus in the midbrain. It is responsible for mediating vertical conjugate eye movements (vertical gaze) and vertical saccades. It mostly projects efferents to the ipsilateral oculomotor and trochlear nuclei.

To mediate downgaze, it projects efferents to the ipsilateral oculomotor nucleus and trochlear nucleus; mediate upgaze, it projects efferents to the contralateral aforementioned nuclei through the posterior commissure.

It is one of the accessory oculomotor nuclei.
